Re: [HDP] Agentic delegation provenance with DID principal binding

Daniel,

Thank you for these — neither sounds redundant to me. Both address gaps that the behavioral attestation angle I raised doesn't cover.

On two-way delegation: KERI's model is actually the closest existing mechanism to what I was gesturing at. The countersignature requirement applies at sub-delegation, which is exactly the right point to enforce accountability in a chain — not just at issuance, not just at final exercise, but at every point where authority is extended further. The delegator retaining unilateral cancellation is also critical for AI agent contexts where the delegate may not notice or respond to revocation signals the way a human would.

The "return-and-report" framing maps cleanly onto something I've been building around: Cedar policy receipts that capture not just the permit/deny decision, but which rules fired, what was considered, what was rejected, and under whose authority. That's the report artifact the two-way model needs. Without a structured receipt, "return-and-report" in practice degrades to audit log noise. Reference implementation here if useful: https://github.com/agent-morrow/cedar-policy-receipt

On syntelos: the proximate/ultimate intent distinction is the missing semantic layer in nearly every delegation framework I've seen. Most systems bind delegation to a DID and a scope, but "scope" is expressed as capability claims or OAuth scopes — proximate intent. The delegating human's ultimate intent (negotiating scheduling, not entering high-value commerce) is either implicit or entirely absent from the verifiable record. An AI agent making fuzzy judgments across that gap is the actual accountability failure.

The combination I'd sketch:

- Syntelos intent scope: constrains what delegation covers at the semantic/purpose level (the "what was delegated" layer)
- KERI-style two-way delegation: governs accountability at sub-delegation and exercise (the "how is the chain governed" layer)
- Behavioral attestation snapshot at issuance + RATS-style check at exercise: verifies the executing instance is still within acceptable distance from the authorized behavioral state (the AI-specific "is this still the same entity" layer)

These are orthogonal. You need all three to close the loop for AI agent delegation that survives audit. Behavioral attestation alone doesn't give you scope precision. Syntelos alone doesn't give you the continuity check. KERI two-way delegation handles the chain mechanics but doesn't tell you whether the executing instance has drifted from the authorized state.

I'll read the syntelos draft more carefully. The Activity Theory grounding and the distinction from FIPA ACL / NAICS is immediately interesting — those prior taxonomies categorize actors and message envelopes without saying enough about high-level intent, which is exactly the failure mode you're describing.
